Application filed May 10, 1915. Serial No. 27,013.

To all whom it may concern.

Be it known that I, ADOLPH THORMAHLEN, a citizen of the United States,residing at New York, in the-county of New York and State of New York,have invented certain new and useful Improvements in Drink- Mixers, ofwhich the following is a specification.

This invention relates to drink mixers and 1 tain or the like, theclerks are usually very busy and it is important that the drink mixingmechanism employed shall be capable of speedy manipulation.

It is a further object of the invention to provide an article of thecharacter set forth employing a plurality of agitators, any of which maybe independently driven so that one or more of said agitators may beemployed at a time for the purpose of mixing drinks.

Further objects and advantages of the invention will be set forth in thedetailed description which now follows.

In the accompanying drawings :.Figure 1 is a view partly in sideelevation and partly in section of a drink mixing machine comprising twoagitators; Fig. 2 is a sectional view illustrating one of said agitatorsin its raised position; Fig. 3 is a plan view illustrating a slightlymodified form of the device employing four agitating mechanisms; andFig. A is a perspective view illustrating a bayonet slot connectionhereinafter described. I

Like numerals designate corresponding parts in all of the figures of thedrawing.

Referring to the drawing, the numeral 5 designates'the casing of anelectric motor, not shown, and to which current may be supplied throughconductors 6 and 7. The motor drives a shaft 8 carrying a bevel frictiongear 9. This gear drives a bevel friction pinion 10, when the bevelfriction pinion is brought into the position illustrated in Fig. 1. Thisbevel friction pinion is carried by a sleeve 11 which rotates in abearing 12 of extension 13 of easing 5. A pin 14 carried by sleeve '11passes through an elongated slot 15 in a stem 16 of agitator 17. A lightspring 18 bears against the lower end of sleeve 11 and normally tends toraise said sleeve, and the friction pinion 10 out of engagement with thefriction gear 9. A cap 19 carries a sleeve 20 which contains a spring 21and a ball 22, said ball bearing against the upper end of the stem 16.The sleeve 20 carrles a pin 23, the inner end of which projects into anannular groove 24 formed in the stem 16, and the outer end of which isadapted to engage in the elongated part 25 of a bayonet slot 26 formedin the bearing 12. The operation of the device is as follows: v 1

Assuming that the parts are in the position as illustrated in Fig. 2, itis apparent that the drinking glass 27 may be placed in positionbeneath'agitator 17. The operator then presses downwardly upon knob 19until the parts liein the position illustrated in Fig. 1. During thedownward movement of knob 19, the top of the slot 15, indicated at 15strikes against pin 14 and forces the sleeve 11 and bevel pinion 10downwardly against the tension of spring 18 until said bevel pinioncomes into operative engagement with the bevel gear 9. It is to beunderstood that the spring 21 is strong enough to accomplish this end.The outer end of pin 23 then enters the bayonet slot 26 and a turn ofthe knob causes said pin to enter. the elongated part 25 of said slot tohold the parts in their lowered position. The factthat pin 23 engagesthe annular groove 24: of stem 16 results in preventing disengagement ofcap 19 from the stem when the parts are in their raised position topermit rotation of the stem with relation to the cap.

The structure shown at the right hand side of Fig. 1 is duplicated atthe left hand side thereof and the same reference numerals have beenapplied. However, the invention is not limited to the use of only twoagitators, but, upon the contrary, four agitating mechanisms may beemployed as illustrated in Fig. 3. In this case 19 designates the capsof agitating mechanism like that shown in Fig. 1, the only difl erencebeing in the number of mechanisms employed, and it is to be understoodthat the number may be varied at will. The employment of the bevelfriction drive as herein shown and described renders it unnecessary toemploy toothed gear wheels which are noisy inoperation, andconsequently, objectionable for use in well fitted establishments.Furthermore, the employment of the bevel gear drive as herein shown anddescribed renders it possible to move the parts into engagement witheach other with a minimum of trouble, and also renders it possible toprovide a plurality of mixing mechanisms and to drive one or more ofthem independently of the other.

\Vhile the elements shown and described are well adapted to serve thepurposes for which they are intended, it is to be understood that theinvention is not limited to the precise construction set forth, butincludes within its purview, whatever is new and within the spirit ofthe appended claims.

Having thus described my invention, what I claim is:

1. In a device of the character described, the combination with arotative driven member, a stem slidable therethrough, an agitatorcarried by said stem, means for driving said stem' from said member,means normally tending to elevate said member, and yielding manuallyoperable means arranged to thrust said member downwardly against theaction of said elevating means.

2. In a device of the character described, the combination with a casinghaving a 1'0- tative bevel gear mounted therein, of a rotative pinionarranged to contact with said gears-a bearing carried by said casing, asleeve carried by said pinion and mounted to rotate in said bearing, astem passing through said sleeve and through said pinion. spring meansnormally tending to elevate said pinion and said sleeve, a pin carriedby said sleeve which passes through an elongated slot in said stem, acap, spring means bearing between said cap and apart of said stem, andmeans for holding said cap against upward movement.

lln a device of the character described,

the combination with a casing having a rotative bevel gear mountedtherein, of a rotative pinion arranged to contact with said gear, abearing carried by said casing, a sleeve carried by said pinion andmounted to rotate in said bearing, a stem passing through said sleeveandthrough said pinion, spring means normally tending to elevate saidpinion and said sleeve, a pin carried by said sleeve which passesthrough an elongated slot in said stein, a cap, means for holding saidcap against upward movement, a spring located in said cap and a ballupon which said spring bears, said ball having a seating upon the upperend of said stem.

4. in a device of the character described,

the combination with a centrally arranged driven bevel gear, of aplurality of beveled pinions arranged thereabout to Contact therewithand be driven thereby. means normally tending to impart upward movementto said pinions, stems passing through said pinions, agitators .carriedby said stems, and manually operable means for thrusting said pinionsdownwardly against the action of their elevating means to bring theminto engagement with said bevel gear as and for the purposes set forth.

5. In a device of the character described, the combination with ahorizontally disposed rotative driving element of a horizontallydisposed rotative driven element, means normally tending to impartvertical movement to said driven element to move the same out ofengagement with the driving element, a sleeve carried by said. drivenelement, an agitator vertically movable with relation to said sleeve torotate therewith, a manually operable member for moving said agitator, afixed bearing member in which said sleeve turns and a bayonet jointconnected between said manually operable member and said bearing member.

6. In a device of the character described, the combination with acentrally disposed beveled driving disk, of a plurality of beveledpinions disposed about the periphery of said disk and movable verticallyinto and out of engagement with the periphery of said disk, sleeves towhich said pinions are connected, a housingfor inclosing said disks andpinions, springs beneath said pinions and bearing between said pinionsand a part of said housing, an agitator rod passing through the sleeveof each of the pinions,a'cap located above each of the pinions, bearingmembers carried by the' housing in which the sleeves of the pinionsrotate, sleeves carried by said caps and projecting into said bearingmembers, pins projecting through the sleeves of the caps, said agitatorrods having cut-out portions in which the inner ends of the pins engage,springs bearing between said caps and the upper ends of the agitatorrods, there being suitably shaped grooves formed in the bearing membersand cooperating with the outer ends of said pins to establish bayonetjoints between the sleeves of the caps and said bearing members.

In testimony whereof ll afix my signature in presence of two witnesses.
